FINGER-RING.

SPECIFICATION forming part of Letters Patent No. 266,869, dated October 31, 1882,

Application filed August 5, 1882. (No model.)

To all whomit may concern Be it known that I, NOAH M1TOHELL,acitizen of the United States,residing at New York, in the State of NewYork, have invented a new and useful Improvement in Finger-Rings, of which the following is a specification.

This invention relates to the construction of those finger-rings which are set with diamonds and other real gems.

ting-mountings bearing precious stones, and especially diamonds, are generally made and worn so as to' show the stone on the bottom of the ring as well as on the top, so as to permit an easy examination of the stone and to expose the same fully. At the same time thisis veryobjectionable to a great many people, owing to the accumulation of dustand dirt, and more particularly, in washing the hands, an accumulation of soap-deposit around and upon the back of the stone, where it cannot readily be reached for removal, as such accumulations materially reduce the luster of the stone and totally spoil its appearance. Manufacturers have tried to overcome this objection by closely hammering the gold to the stone, and thus making the joint around the stone at the top of the ring dust-tightand water-tight; but this only partially meets the difficulty. Others have closed up the back of the ring entirely, showing nothing of the stone but the surface on top of the ring.- This is still more objectionable, as it is successfully used inproducing imitation rings, and purchasers of real stones demand settings which will show their size and value when there is occasion to convince others. Ihave overcome all these objections and difficulties by a neat and simple combination of parts in a ring set with one or more precious stones, as hereinafter described and claimed.

In the drawings which accompany this specification, Figure 1 is a side view of a solitaire diamond ring illustrating this invention, and Fig. 2 is a sectional view of the same,with its stone-protector removed. Fig. 3 is a top view or front view of the ring; and Fig. 4 is a perspective back view, showing the stone-protector in position. Figs..5 and 6 are detail viewsof the stone-protector, and Fig. 7 is a side view .of a lever-key for use in removing and replacing said stone-protector.

Likeletters of reference indicate corresponding parts in the several figures.

The external appearance of my ring maybe ordinary or identical with that of any other ring having a close setting, as indicated by Figs. 1 and 3. The ring is composed ofa gold body, B, of the desired design, a suitable stone or stones, S, ofany preferred variety, and a stone-protector, P, of any suitable material. The body'B is provided with a stone-seat, a, fitted to the customary angular rim of the stone S, (or each stone,) and upon this the stone is solidly secured by an overlying close rim, I), of gold, formed by hammering the gold tightly around the stone, as in forming other close settings. This makes a dust-tight and watertight joint around the stone at the top of the ring. An internally-screw-threaded circular opening, a, perpendicular to the said stoneseat a, accommodates the back of the stone S, (or each stone,) and receives the matching stone-protector P, as illustrated by Figs. 2 and 4. The stone-protector P, as shown in Figs.2 to G,is an externally-threaded screw-plug, tightly fitted to the said opening 0. lt has a recess, (7, in its upper end to accommodate the back of the stone, so as to be made of sufficient length withoutmateriallyincreasing the depth of the top of the ring, and its lower end is shaped, as indicated at c, Fig. 2, so as to complete the internal surface of the ring without apparent breakin said surface, and is provided with indentations f, to which projectionsg on a little lever-key, K, Fig.7, are fitted. A key of this description should accompany each ring in its case, to be carried in the pocket, or as a charm,if desired, so as to facilitate the removal and replacementof the stone-protector by the wearer at will. \Vhen said stone-protector is in place it tightly closes the opening behind the stone, rendering the back of the ring dust-tight and water-tight, so as to per- -mit no dirt of any sort to reach the stone from that side, and thus cooperates with the close setting at the top of the ring to keep the stone clean and to preserve its original luster. WVhen the stone-protector is unscrewed and removed from the ring, as shown in Fig. 2, the stone is seen lying substantially bare for examination or valuation, while the setting of the stone is undisturbed.

Having thus described my said invention, I and a removable stone-protector in the form 10 claim asnew and desire to protect by Letters of a matching screw-plug, which, when in p0- Patent--- sition, tightly closes said opening behind the In a finger-ring, the combination of a ringstone, substantially as herein specified, for the 5 body constructed with a stone-seat at the top purposes set forth.
